Australia is Probably the Most suited country to use solar, Tidal, Wind and Pump Hydro. Remote inland places could be a Virtual independent Oasis off grid and entirely Airconditioned with solar and batteries. Big tides near Broome etc could be harnessed. We could have it ALL with a bit of foresight. Electric..... Silent non polluting and vibrationless Instant starting no warm up and regenerative,. When in all of history has such things been Possible and so available.? Nev
